CRP and COVID-19: This categorization aligned with various clinical parameters, including the lowest value of the ratio of arterial oxygen partial pressure (PaO2 in mmHg) to fractional inspired oxygen (FiO2 expressed as a fraction, PaO2/FiO233) (Supplementary Figure 1A), Absolute Lymphocyte Counts (ALC, Supplementary Figure 1B), as well as other inflammatory biomarkers associated with COVID-19 progression such as lactate dehydrogenase (LDH) and C-reactive protein (CPR) (Supplementary Figures 1C, D).
